You Said 'We'll Fast-Follow.' They Heard 'It's Coming Next Sprint.'

The quarterly roadmap review was going smoothly. Too smoothly. Then the VP of Sales shared his screen. "This is a must-have for our biggest enterprise prospect. Can we get it in?"

It was a good idea. It was also a massive engineering effort that wasn't on the roadmap. You knew it, your engineering lead knew it. But you didn't want to shut down a VP in front of everyone. So you said the magic words: "Great idea. It’s too late for this quarter's plan, but we’ll fast-follow with it."

The VP smiled. Your Eng lead gave you a look you couldn't quite decipher. The meeting moved on. You mentally patted yourself on the back for defusing a tense moment and protecting the sprint.

Three weeks later, an email hits your inbox. "Following up on the 'fast-follow' feature. The prospect is asking for a demo date. Where are we at?"

You've just discovered the danger of a perfectly ambiguous promise. To you, "fast-follow" meant "a good idea we'll consider for the next roadmap." To sales, it meant "the very next thing you're shipping after this quarter's stuff." Your engineering team heard nothing at all, because it never became a ticket.

You didn't create alignment. You created three different versions of reality.

The Jargon That Destroys Roadmaps

We do this all the time. We use fuzzy language to avoid conflict or to keep our options open. Phrases like "fast-follow," "on the radar," or "Phase Two" are convenient shields. They feel like a soft 'yes' to the stakeholder and a soft 'no' to the engineering team.

In reality, they are vacuums of meaning. Stakeholders fill that vacuum with their own priorities and timelines.

This happens for two reasons:

1. The Optimism Gap: You are painfully aware of every dependency, piece of tech debt, and competing priority that stands between an idea and its execution. Your stakeholder is painfully aware of their one problem. When you give them an ambiguous answer, they don't hear the constraints. They hear the commitment.
2. Lack of a Shared Dictionary: You never defined what "fast-follow" means. Does it mean next week? Next
